A sneezing cat is typically not considered an emergency or serious problem unless it happens frequently or is associated with abnormal discharge such as blood. Seeing a cat sneezing blood can be a very scary experience.
While a little blood can be harmless, seeing blood consistently or frequently can indicate a concerning issue and should be considered an emergency situation. There are many causes of sneezing blood, commonly referred to as epistaxis, or a bloody nose.
What It Means If A Cat Is Sneezing Blood?
Cats will sneeze for a variety of reasons. Excess nasal discharge or fluid in the nasal passage can cause a tickle leading to a sneeze. Strong or new smells can make a cat sneeze, as can allergies, upper respiratory infections, or foreign material up the nose causing irritation. But what does it mean if your cat is sneezing blood?
A nosebleed, commonly termed “epistaxis,” is caused by the blood vessels in the nasal passage breaking, bleeding, and leaking out the nares, or nostril. The bleeding itself can cause some mild irritation leading to a bout of sneezing. If there is enough blood, it can cause a bit of a mess. There are many different diseases or disorders that can cause epistaxis leading to sneezing blood such as infections, inflammation, foreign bodies, or allergies.
It is important that, if the sneezing is persistent, if there is a large amount of blood, or if the cat is acting sick, that you bring the cat to your veterinarian for treatment right away.
Causes of A Cat Sneezing Blood
Sneezing blood, or epistaxis, can be caused by a variety of conditions. Some are critical, while others are mild.
1. Upper Respiratory Infections
An upper respiratory infection, or cold, can be caused by a variety of different bacteria or viruses. These are common in cats and kittens as they are rather contagious between cats. This is one of the most common causes of sneezing in cats.
Because upper respiratory infections are easily transmitted between cats, they are found most commonly in places with a large number of cats such as shelters, rescues, boarding facilities, and catteries.
Most of the common bacteria and viruses that cause upper respiratory infections can be prevented with appropriate and complete vaccination, as many of the inciting viruses are included in the kitten’s vaccine series and given yearly or every few years throughout the cat’s life.
The most common viruses causing upper respiratory infections are Feline Herpesvirus and Feline Calicivirus.

The Feline Herpesvirus is contagious between cats but not people. Symptoms are usually brought on by stress and include sneezing, nasal discharge, runny eyes, eye infection (conjunctivitis), cough, or congestion.
Feline Calicivirus has similar symptoms but also commonly causes ulcers in the mouth or nose.
Both of these viruses can range from mild symptoms which are treatable at home but can also become severe needing management in the hospital. Often, a bacterial infection can start requiring antibiotics in addition to treating the other symptoms.
If a raw nose, ulcers, or excessive sneezing occurs, blood can be seen in the nasal discharge.
2. Fungal infections
Cats cat get fungal infections if they inhale an excessive amount of a pathogenic fungus or if they have a compromised immune system.
The most common fungus to cause a nasal infection in cats is Cryptococcus neoformans. This causes swelling of the nose, destruction of nasal tissue, nasal discharge, sneezing with or without blood, and other symptoms of upper respiratory infections.
3. Clotting disorders
Platelets are important blood cells that help the blood clot when there has been an injury. If the process of clotting is disrupted, or if there is something wrong with the platelets, it becomes more difficult for the bleeding to stop.
Rat poison is a common cause of such clotting disorders. Toxic ingestion of rat poison or ingestion of a small animal (mouse) that has eaten the rat poison, can be deadly. If a cat eats an anticoagulant rodenticide, there are antidotes if treatment is sought out immediately.
Other causes of clotting disorders and low platelets in cats include liver failure, inherited clotting diseases such as hemophilia, viruses such as Feline Leukemia and Feline Immunodeficiency viruses, immune-mediated thrombocytopenia, cancer, bone marrow diseases, and rare drug reactions.
The quickest way to find out if there is a problem with the platelets or other clotting and blood disorders, is to perform blood work checking platelet and red blood cell counts.
A cat might be sneezing blood if there has been some kind of accident or injury to the face. This might be from a fight with another animal, a car accident, or other trauma where the head or face has been injured.
5. High Blood Pressure
Cats with high blood pressure may exhibit nose bleeds and sneezing blood. High blood pressure, or hypertension, occurs when the pressure of blood flowing through a vein is simply too high for the vein to withstand, this can cause excessive bleeding or clots. This issue can become worse when a cat is stressed.
There are a variety of cancers that can be found in the nasal passages, face, or sinuses in cats. These can cause swelling, destruction of the nasal tissue, bleeding, infections, sneezing, and a bloody nose.
To find out if cancer is the cause of the sneezing or mass, a sample, known as a biopsy, is taken by the veterinarian and sent to a laboratory. Once there is a diagnosis, it can be determined if the cancer is treatable.
7. Foreign Material and Inhaled Irritants
Irritants or small objects that are inhaled through the nose and enter the nasal cavity can cause sneezing and even trauma to the sensitive tissue inside. The excessive sneezing and trauma can cause bleeding.
Some common foreign material that can be inhaled include dust, pollen, small pieces of grass or other plants, bugs, or other debris. These foreign objects must be retrieved through rhinoscopy, or video scoping up the nasal cavity.
Irritants that cats can be sensitive to when inhaling them include cigarette smoke, perfumes, sprays, cleaning agents, dust, mold, scented candles, and smoke from other sources.
Be cautious when using any of these materials around your cat.
Polyps are small benign masses, or growths, that can be found in the nasal passages, ears, soft palate, or throat. These can become irritated and bleed.
9. Autoimmune Disease
Cats can get diseases that affect their immune system in various ways. These can be systemic or internal disorders, diseases affecting the blood cells, or conditions affecting the skin.
Common allergies such as pollens, weeds, and dust can cause nasal irritation, sneezing, and a dry nose leading to a bloody nose.
What To Do If Your Cat Is Sneezing Blood?
If you notice that your cat is sneezing blood, the first and most important thing to do is to stay calm. Cats are quick to pick up on stress and are likely already stressed because of their excessive sneezing and their nose bleeding. Staying calm while still acting quickly will help keep your cat’s stress level, and blood pressure, down.
- Catch the cat. Cats that are scared or stressed will often run away or hide. Find the cat and hold it or confine it in a small, quiet area as quickly as possible.
- Cats don’t typically tolerate any home remedies or solutions, so if the bleeding doesn’t stop or there is an excessive amount of blood, the best thing to do is to quickly take your cat to see your veterinarian. Even if there is only a minor issue, it is better to address it right away before it becomes a bigger problem. If something concerning is discovered, then treating it right away is critical.
- If the cat allows it, applying a cold compress, such as an ice pack, to the top or sides of the cat’s nose may help slow or stop the bleeding. Cleaning the face or nose with a cool damp cloth can also be helpful. Avoid these steps if it causes more stress and always ensure that you don’t obstruct your cat’s airway and ability to breath freely.
- It is important that you do not stick anything up the nose. This could cause more damage and could overly stress the cat.
- Make note of when your cat started sneezing blood, how long it lasted, if it is from one or both nostrils, any medications the cat is taking, and any accidents or injuries that occurred.
While there are many reasons a cat might sneeze blood, the important things to remember are to stay calm and seek veterinary care to get to the bottom of the problem.
